3% morphology

Hi ladies. I've recently started seeing a new OB and she has referred me and my husband to Fertility Answers. My husband had a Semen Analysis done and his morphology came back at 3%. My OB wants to see it >/=4%. She has started him on 1,000 mg of Vitamin C twice daily. I have a HSG scheduled for Monday. We've had 4 consecutive miscarriages in the last year and have no living children. I also have Factor V Leiden and MTHFR. We know we can get pregnant, but unable to conceive since our last miscarriage in April. I guess what I'm asking if any of you ladies had this problem with SO/husband and have had a healthy baby to term. Please share your stories. 💜
